执行helm包的安装，需要自定义配置文件，也就是values.yaml。我们可以先行下载 mysql chart包。
global.storageClass=hostpath 可通过kubectl get sc查看集群支持的storageClass，我这边选择默认的hostpath。其创建的pv的默认回收策略为delete，也就意味着卸载mysql，数据直接删除，这点需要注意！！！如果需要保留测试数据，请更新storageClass。

Tip:
Watch the deployment status using the command: kubectl get pods -w --namespace db

这里要记住上面的meta service url：http://apollo-dev-svc-apollo-configservice.apollo:8080
那如何确认正确部署了呢：

指定配置源 ，主要是envs和metaServers两个配置项： config.envs=dev config.metaServers.dev=http://apollo-dev-svc-apollo-configservice.apollo:8080（上面部署apollo service输出的apollo service url）如果同时启用开发、测试和生产环境。可以配置为：envs: "dev,uat,prd"，metaServers 分别指定对应环境的配置即可。 以下是只启用开发环境的配置：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
